• Drill the eight holes, using a drill or percussion drill with a bit
appropriate to the substrate material (masonry/concrete, wood,
steel etc.) with the appropriate diameter and to the appropriate
depth for the anchor type being used.
• Once the eight mounting holes have been drilled, clear them of
residue and verify the appropriate depth of each.
• Place the Angle Bar/yoke assembly against the wall in the
correct orientation (with the open "hooks" for the angle-
adjustment plates facing up) and align the eight mounting holes
centered on the drilled holes.

• Insert the eight screws or anchors through the mounting holes
in the Angle Bar. Tighten the screw anchors with your fingers
only sufficiently to keep them in place.

a power screwdriver to tighten each anchor, until each holds
the plate to the wall. Due o the shape of the Angle Bar, it could
be difficult to use a power driver for the four screw anchors
nearest the attachment for the yoke. It could be necessary to
use a simple spanner or wrench to drive in these anchors. When
using a power driver, keep it at a low speed to avoid stripping
the threading cut into the substrate material. Once the washer
or flanged head on each bolt is in contact with the bracket and
the bracket is against the wall, continue tightening them only
by hand.
